EPECEPICATION forming part of Letters Patent No. 318,588, dated May 26,1885.

Application filed October 17, 1884.

To all whom, it may concern.-

Be it known that I, CHARLES F. WOLF, of Terre Haute, in the county ofVigo and State of Indiana, have invented certain new and usefulImprovements in Heating and Drying Ovens; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the figures and letters of reference markedthereon.

My invention has for its object to provide animproved oven for dryingclothes, fruit, &c., and which shall also be adapted to the baking ofbread and other articles of food, such oven to be heated by gas, or by acoalstove, oil-stove, or other convenient source of heat-supply.

I will first describe my invention at length, and then point out itsparticular features of novelty in the claims at the end of thisspecification.

In the accompanying drawings, Figure 1 rep resents a perspective view ofmy improved oven with one of the sliding racks pulled out. Fig. 2 is ahorizontal section of the same; Fig. 3, a longitudinal section taken onthe line as a, Fig. 2.

Similar letters of reference in the several figures indicate the sameparts.

The letter A indicates the body of the oven, consisting of a chamber ofany desired size, formed preferably of wood and lined with galvanizediron, and with orwithout one or more air-spaces Within its walls. Thebottom of this chamber consists of a metal plate, B, having a largecentral hole, C, for the admission of heat, and having also a series ofsmaller openings, D, for ventilation purposes, as will be further onexplained. Upon this bottom B is arranged a heat-chamber, E, constructedin the form of an inverted drawer, and adapted to be slid in and outthrough one of the side walls of the chamber when desired. A pipe, F, isattached to the rear of this heat-chamber, and when the said chamber isslid in is adapted to project into a corresponding pipe, F, passingthrough the side of the chamber A and leading out into the open air. Thesaid heat chamber is further provided with a flange,

G, which projects fromits sides and inner end,

(No model.)

and rests upon the bottom plate, B. A series of openings, G, are formedin this flange G, and when the chamber is slid to the proper positionthese openings H register with the openings D in the bottom B, andafford direct communication between the outside and the interior of thechamber A, though when the heat-chamber is moved slightly the saidopenings do not register and the communication with the outside is cutoff. Within the heat chamber, opposite the opening in the bottom plate,B, through which the heat enters, is arranged a deflector, I, thefunction of which is to prevent the entering heat from striking directlyupon the top of the heat-chamber, but instead to be deflected laterallyto the extremities of the heat-chamber, and thus diffuse it.

\Vithin the main drying-chamber are arranged two sets of cross rods orbars, J K, the former being arranged slightly above the top of theheating-chamber, and being supported at one end by the wall A of thechamber and at the other end by a cross-piece, L, while the latter (K)are arranged near the top of the chamber, and are likewise supported atone end by the wall A and at the other end by a cross-bar, M. Theseupper and lower crossrods, K and J, serve as guides for a series ofsliding racks, O. The inner vertical pieces, P, of these sliding racksare slotted at their lower and upper ends for the accommodation of theguide-rods K J, while the outer vertical pieces of said racks, when theracks are slid in, abut against each other and constitute the wall ofthat side of the drying-chamber, their lower ends resting upon the endof the heat-chamber. Each rack is provided with a suitable handle, Q, bywhich it can be conveniently slid in and out. I form suitable shoulders,R, upon the lower guide'rods, J, near the cross-pieces L, and when theracks are drawn out to their fullest extent their inner vertical piecespass these shoulders and drop down behind them, the slots in the piecesP being made slightly longer than the guide-rods, so as to allow of thislimited up and down movement, and the racks are maintained in verticalposition and prevented from sagging by the backsioo ble glass door, Athrough which the contents of the chamber can be inspected while thedrying operation is going on. Heat might be supplied to the heat-chamberby placing the chamher over any suitable open fire, stove, gas-stove, oroil-stove; or one or more gas'jets may be lighted beneath the opening Gin the lower plate,B,leading to the heat-chamber. If smoke enters theheat-chamber, it will pass out readily through the exit-pipe F into theopen air, and if it is desired to regulate the amount of heat flowingthrough the heat-chamber it can be done by manipulating the damper S,arranged in the said pipe F.

In order that requisite ventilation may be given the interior of thedrying-chamber, the heating-chamber may be shifted so as to cause theopenings D G to register, and a proper circulation can be effected byadjustment of a damper, T, which is arranged in a pipe, U, that leads tothe open air from the top of the dryingchamber. XVhere clothes are to bedried, they are hung upon the racks, and the latter are shifted intotheir places within the chamber, and but a short time will be requiredto thoroughly dry them. Where fruit is to be dried or bread or otherarticles cooked, the material may be placed on trays and the latter slidin upon the cross-bars of the rack through the open door.

I have found from practical tests that light goods canbe driedthoroughly in from twenty to thirty minutes and woolen goods in fromforty-five to sixty minutes without the slightest injury to the textureof the goods or to their color. I have also found that fruit might bedried and bread and pastry baked within the oven with most satisfactoryresults.

Having thus described my invention, what I claim as new is 1. Thecombination of the drying-chamber having the opening in its bottom platefor the ingress of heat and also the ventilation-openings,andtheslidingheating-chamberprovided with a discharge-pipe, and having theventilatingopenings in its flange corresponding with theventilating-openings in the bottom plate of the main chamber,substantially as described.

2. The combination, with the drying-chamber, of the upper and lowerhorizontal guiderods, the latter being supported at one end by thecross-bar L and having the shoulders arranged near the said cross-bar,and the sliding racks adapted, when drawn out to their fullest extent,to be supported in a horizontal position and prevented from sagging bymeans of the shoulders on the said guide-rods, substantially asdescribed.
